Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| North-facing solar panels are not effective. | While south-facing solar panels may receive more direct sunlight, north-facing solar panels can still generate a significant amount of energy. In fact, in some regions with high levels of diffuse light (such as the Pacific Northwest), north-facing panels may actually be more efficient than south-facing ones. It ultimately depends on the specific location and climate conditions. |
| South-facing solar panels always generate more power than other orientations. | While it is generally true that south-facing solar panels receive the most direct sunlight throughout the day, this does not necessarily mean they will always produce the most energy overall. Factors such as shading from nearby trees or buildings, panel tilt angle, and local weather patterns can all impact how much electricity your system generates regardless of orientation. A professional installer can help you determine which orientation is best for your specific situation based on these factors and others like them. |
| Solar panel installation should only be done on roofs facing one direction. | This is a common misconception that limits homeowners‘ options when it comes to installing solar systems on their property. In reality, there are many ways to install solar panels beyond just roof-mounted arrays facing one direction – ground-mounted systems or carport installations are also viable options depending on available space and other factors unique to each property. |
| The cost difference between north- and south- facing installations is negligible. | Depending on where you live and what type of system you’re installing, there could be a significant price difference between north- vs south- facing installations due to differences in equipment costs or labor expenses associated with mounting hardware placement or wiring configurations needed for optimal performance under different orientations. |
